Re: File Encryption AES-128 versus AES-256?

If AES-128 is so insecure than AES-256, then why is it approved by the US Air Force as decribed the link I posted?

Dont understand.

I don't understand what you're saying. No. AES-128 is NOT considered insecure. Far from it.

The best published attacks take the relative security down by 2 bits, or say AES-126. Still not practical to attack, even with a global cluster of supercomputers.

As for standards? It's possible that a military would require far stronger encryption than what is currently strong. They might have an interest in keeping their secrets safe 20, 30, 50 years into the future.
